Issue

Three dimensional objects, including regions, solids, meshes, objects drawn by extruding or revolving, Boolean operations, and solid models can all be converted into polyface meshes or 3D faces.

Solution

To convert these type of objects:

1. Use the 3DSOUT command to export objects from a drawing. Use the default settings.
2. Open a new drawing.
3. Enter 3DSIN on the command line.
4. Select the new drawing you just created.
5. From the 3D Studio Import Options dialog box, choose the Add All button.
6. Choose OK.

The objects will load into the drawing as polyface meshes.

To create 3D faces from the polyface meshes, explode the polyface meshes.
